HOSE-PATCHV QPECIPICATION forming part of Letters Patent No. 358,618, dated March 1, 1887.

- Application filed October 2, 1886. Serial No. 215,190, (No model To all whom it may concern.-

Be it known that I, WILLIAM H. LooMIs, of Alameda, Alameda county, State of California, have invented an Improvement in Hose-Patches; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to a device for repairing weak or broken places in hose or pipe.

It consists of a cylindrical flexible section of sufficient size to surround the hose or pipe to be mended, and an arrangement of tongues or buckles by which it is held at any desired degree of compression, and a means for closing or compressing it upon the part to be mended, all of which will be more fully explained by reference to the accompanying drawings, in which- Figure 1 shows one form of my device with the edges separated and the key removed. Fig. 2 shows the device applied to a hose and the keyin place. Fig. 8 shows a modification of the device for producing essentially the same result.

A is a sheet of flexible material, made of sufficient-size to clasp around the hose orpipe which is to be repaired, and having one edge, a, folded back upon itself, so as to leave asmall channel in the fold, as shown. Near this edge are slots or openings B, of sufficient size to re ceive tongues O, which project from the opposite edge of the sheet in such relation with the slots that they may be introduced into them when the sheet has been folded around the hose or pipe to be mended.

Small lugs oriudentations c are made in each of the tongues C, so as to project inwardly, as shown.

The operation is as follows: The sheet of metal A, being long enough to cover any weak or fractured place in the hose or pipe, is folded around the latter at the point of breakage, so that the break is inclosedinthe' unbroken part of thesheet A, themceting edges being brought together as nearly opposite to the break as possible. The tongues O are then introduced into the slots B, and a wedgeshaped piece, D, is introduced from one end, so that one edge will fit or travel into the groove formed by the turned-back edge a of the plate A, while the other edge of the wedgeshaped piece engages with one or another of the rows of projecting lugs a, before described.

The position of the channel a with relation to the rows of inwardly-projecting lugs c is such that when the wedgeshaped piece 1D is driven in so as to engage the channel and the lugs it will cause the projecting tongues G to be forced farther into the slots B, which are made for them, and will draw the sheet of metal tightly around the hose, thus causing it to clamp the latter firmly, while leaving a perfcctly smooth exterior surface, not liable to catch or tear anything with which it may come in contact.

The lugs 0 being made in rows atashort dis.

tance apart, it will be manifest that the wedge may be made to engage any row of lugs, depending on the size of the hose around which the clamp or sheet a is placed, and as the point engages one of the series of rows when the wedge is driven through, it will engage all the lugs in that row, and will thus draw the clamp on as tight as may be desired.

In Fig. 3 I have shown a modification in which the metal is cut away on three sides to form the slot B, and the short tongue thus formed issimply pressedinward, so that a sort of tongue projects into the slot from the side nearest the edge of the sheet A. The tongue 0 in this case being provided with the same lugs c, as before shown, these lugs will engage with the inwardly'projecting tongues B of the slots B, and will thus form a lock, holding the band tightly wherever it may be placed. In order to draw this band closely about the hose, the edges a are turned backward between the tongues O, and outwardly-projecting lugs 01 are formed upon the sheet A and behind the slots or openings B. In this case the clamp or wedge D has one edge turned under, so as to engage the lugs d, and the other edge has rows of inwardly-projecting lugs, which engage the outwardly-turned edges a, before described, and when driven upon the tube, which has been formed byintroducing the tongues G into the slot B, it will act to draw the parts together, clamping them firmly upon the interior of the hose or tube, and the small projecting lugs c in the tongues G will engage with the edges of the inwardlyprojecting plates B, thus holding the device at any desired point to which it may be drawn. This Wedge-shaped clamp D is driven on from one end, and serves to draw the tube closely together. It maybe then left in position, or may be taken off, leaving the clamp in place, and the projecting lug d and the turned-over edges to may be flattened down or otherwise prevented from projecting so as to be in the Way.

Various modifications of this device may be used; but the principle involved, which lies in the small projecting lugs or tongues, either row of which may engage so as to buckle or look the clamp around various sizes of hose, is the feature of my invention.

Having described myinvention, what I claim as new, and desire to secure by Letters Patent, 1s

The flexible cylindrical sheet or band surrounding the hose or pipe and having slots or openings made in one edge, and the tongues projecting from the opposite edge with the inwardly projecting supplemental tongues or lugs c, in combination with the wedge-shaped piece which is driven from one end so as to engage the lugs, whereby the clamp is drawn together and compressed upon the hose, substantially as herein described.

In Witness whereof I have hereunto set my hand.

W. H. LOOMIS.
